Problems solved by technology

At present, the start and stop of the fuel cell is mainly based on the current driving mode, the power requested by the power system, the allowable output power of the power battery and other thresholds to judge the timing of the start and stop of the fuel cell. If the driver's driving habits are poor, it will cause the fuel cell to start and stop too frequently , will not only consume too much power of the power battery, but also affect the life of the fuel cell

Abstract

The invention relates to the technical field of vehicle control, and provides a method and device for controlling the fuel cell of a vehicle. The vehicle comprises a fuel cell and a power cell. The method comprises the following steps: detecting road condition information of a planned driving route of the vehicle; detecting the electric quantity of the power cell; and controlling the fuel cell to start or stop according to the road condition information and / or the electric quantity of the power cell. The electric energy of the power cell can be saved, and the service life of the fuel cell is prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a method and device for controlling a fuel cell of a vehicle. Background technique [0002] The fuel cell (such as hydrogen fuel cell) vehicle will involve the start and stop of the fuel cell during use. At present, the start and stop of the fuel cell is mainly based on the current driving mode, the power requested by the power system, the allowable output power of the power battery and other thresholds to judge the timing of the start and stop of the fuel cell. If the driver's driving habits are poor, it will cause the fuel cell to start and stop too frequently , not only consume too much electric energy of the power battery, but also affect the service life of the fuel cell. Contents of the invention [0003] In view of this, the present invention aims to propose a method for controlling the fuel cell of a vehicle, so as to save the electric energy of the power batte...
